RUNNING-GEAR FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 461,940, dated October27, 1891.

Application filed June 30, 1891. Serial No. 398,061. (No model.)

To all whom it may con/cern.-

Be it known that I, REMEMBRANOE LINDSAY KIRBY, a citizen of the UnitedStates, residing at Pomeroy, in the county of Garfield and State ofVashington, have invented a new and uscful Running-Gear, of which thefollowing is a specification.

The invention relates to improvements in running-gears.

l The object of the presentinvention is to simplify and improve theconstruction of running-gears, especially the connection between thefront bolster and the front hounds, and 'to provide means whereby anywear of the kingbolt may be readily taken up to retain the bolster inproper position and to prevent breakage of the king-bolt by the parts ofthe running-gear assuming an unnatural position.

A further object of the invention is to prevent the reach andthecross-bar connecting the rear ends of the front hounds becoming worn byrubbing against each other in turning the vehicle.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying-drawings, and pointed out in the claims hereto appended.

In the drawings, 'Figure l is a perspective view of a portion of arunning-gear constructed in accordance with this invention. Fig. 2 is avertical longitudinal sectional view. Fig. 3 is a detail sectional viewon line fr x of Fig.

2. Fig. 4 is a detail perspective View of the 'bearing-box, the sectionsbeing swung apart.

Referring to the accompanying drawings, 1 designates a front axle, 2fronthounds, and 3 a bolster,which is connected with a cross-bar 4,arranged at the front e'nd of the hounds 2 and connecting the same by anadjustable block 5, secured to the bar 4, and a plate 6, attached to thefront face of the bolster 3. The plate 6 is provided with a horizontalflange 7 formed integral with it and having a curved opening 8, in whichis arranged an anti-friction roller 9, which is mounted in a bifurcationl0 of the rear end of the ad j ustable' block 5. The block 5 isroughened or serrated at the lower face of its front end, and thissurface 11 is secured upon a similar surface 12 of the cross-bar 4c bymeans of a set-screw 13,which passes through a longitudinal slot let ofthe adjustable block, whereby the block is adapted to be movedlongitudinally to take up any wear and to enable the bolster 3 to bemaintained in its proper position to prevent the king-bolt 15 beingbroken by the parts of the running-gear assuming an unnatural position.This construction is especially adapted for rough roads and hillycountries where vehicles are jolted to a considerable extent.. Theroller 9 bears against the curved edges of the openin g 3 and enablesthe vehicle to be readily turned without friction or wear of the part-s.The reach 16 has secured to its lower face a bearing-box 17, which hasopen sides and is provided at its top and bottom wit-h anti-frictionrolls 18 and 19, arranged above and below the cross-bar 2O to preventfriction and wear on the same and the reach when the vehicle is turned.The cross-bar 2O passesthrough the open sides, and the box is composedof two sections 21 and 22, the former of which is secured to the lowerface of the reach and is provided with depending perforated ears 23 `andthe latter has perforated lugs 24: and 25.

The lug 24 is hinged between the adjacent ears 23 by a pintle 26, andthelug 25 is secured between the adjacent ears 23 by a removable pin 27,adapted to be withdrawn to permit the sections to be separated, wherebythe reach may be readily removed and replaced. The anti-friction rolls1S and 19 have their ends reduced and journaled in suitable bearings atthe ends of the sections, and each section has an open bearing to enablethe rolls to be readily taken out when the sections are separated.

It will be seen that any wear of the king-bolt or its bearings may bereadily taken up to maintain the bolster in proper position, therebyenabling vehicles to be successfully employed in rough and hillycountries without danger of the king-bolt being accidentally broken bythe parts of the running-gear assuming an unnatural position. lt willalso be seenthat all wear of the .reach and the crossbar which connectsthe rear end of the front hounds is prevented and that the sections ofthe bearing-box may be readily swung apart to permit the reach to beremoved. The curved opening forms a curved bar at the front of theiiange of the plate, and, if desired, a curved IOC rod may be employedinstead of the flange and be suitably secured to the plate and bearranged in the bifurcation to engage the roller.

It will be seen that both of my improvements may be applied to anyvehicle withoutcutting or marring the same, and, in fact, Without makingany change of any description.

What I claim is- 1. The combination, with a running-gear, of the platesecured to the front bolster and provided with a curved opening and ablock adjustably mounted upon the hounds and provided With a rollerarranged in said opening, substantially as described.

2. The combination,with a' running-gear, of

the plate secured to the front face of the front bolster and having aange provided with a curved opening, a block having its rear endbifurcated and provided with a roller arranged in said opening andprovided at its front end with a slot, and a set-screw arranged in saidslot, whereby the block is adjnstably secured in place, substantially asdescribed.

3. The conibinatiomwith a runninggear, of a plate secured to the frontbolster and provided With a curved bar and a block adjustably mountedupon the hounds and engaging the curved bar, whereby the bolster ismaintained in proper position, substantially as described.

4. The combinationgwith a running-gear, of

a bearing-box secured to the lower face of the bearing-box secured tothe lower face of the g reach and having open sides to receive thecross-bar connecting the rear ends of the front hounds and provided withsuitable bearings, and comprising the upper section 2l, secured to thereach and provided with depending perforated ears, the lower sectionprovided with perforated lugs 24 and 25, a pintle hinging the lugs 24Ebetween the adjacent ears, a removable pin securing the lug 25 betweenits adjacent ears, and anti-friction ears journaled in said bearings,substantially as described.

ln testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

REMEMBRANCE LINDSAY KIRBY.
